It seems i cannot get a clear answer wherther it is possible to limit a CPU usage by a user process and should i do that at all. I just wana run "tar -xzvf /usr/backup/pub.tar.gz /usr/home/pub" and do not cause something like this: PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU 3993 backup 139 20 8672K 8068K RUN 19:56 87.65% 87.65% load averages: 0.99, 0.98, 0.88 As you can see in the figure above, renicing wont work. Any hints? What to read? Thank you.
